Application filed December 28, 1915.

To all whom it may concern:

Be it known that I, SIMON Go'rrnrnn, a subject of the Emperor of Austria-Hungary, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Disk-Cutters, of which the following is a specification.

This invention relates to improvements in apparatus for cutting textile fabrics into circular disks and particularly for such fabrics or other material as are adapted to be used as button coverings.

The principal object of the invention is to provide an apparatus in which can be clamped a plurality of fabrics or other material one above the other, forming a stack, clamping the same rigidly in this condition and cutting through the entire series with a knife, caused to rotate within the prescribed area, the same being manually operated and capable of expeditious and accurate operation. This and other objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawing, forming a material part of this specification, and in which Figure 1 is a partial elevational, partial vertical sectional view of a machine made in accordance with the invention. Fig. 2 is a transverse sectional view, taken on line 2-2 of Fig. 1. Fig. 3 is a similar sectional view, taken on line 33 of Fig. 1. Fig. 4. is a fractional bottom plan view, looking up on line t1- of Fig. 1, and Fig. 5 is a view, taken on line 55 of Fig. 1.

The machine is housed in a frame, comprising two sides 10 and 11, adapted to be secured on any level foundation, as a bench or counter by screws passing through the feet 12, the said members being connected at the top by a rail 14.

A cylinder 15 provided with arms 16 by which it is rigidly secured to the side fames 10 and 11, is arranged centrally of the machine and contains a screw-thread 17, extending the entire length of its interior. Fitted to these screw-threads is a cross-head 18, driven rotatably by the arms 19, the lower ends of which are formed integral with the bevel gear 20 so that as the latter is turned, the cross-head is caused to rotate. Motion is communicated to the bevel gear 20, by means of the pinion 21 mounted on Specification of Letters Patent.

the shaft 22, housed in bearings formed with the frame side 11, and provided with an operating means as the crank 23, as shown in Fig. 1. Obviously, the shaft may be driven by power if desired.

Secured in the cross-head upon opposite sides thereof, by means of the clamp screws 26, are knives 28, extending vertically downward within the cylinder 15, having beveled cutting edges 30 on their extreme lower ends and it will be obvious that these knives are caused to move vertically within the cylinder, whenever the crank 23 is actuated. At the same time, they are further caused to rotate in a circular pathway within the cylinder.

The gear 20 is supported on the cross bar 32, extended between the side frames 10 and 11, it having an annular hub 38, rotatable within the widened disk like portion of the bar 32, so as to be guided thereby. Another cross-bar 85 is rigidly secured to the side members, near their lower ends and carries at its center a clamp screw 36, provided with a hand-wheel 37, the point of the screw 36 extending above the bar and engaging with a hub 39 from which the arms 38 radiate, these arms being operatively engaged with a bar 40, provided with elongated ends 41, adapted to slide in the guide-ways 42, formed with the side frames 10 and 11. The bar 10 is enlarged at its center and formed with a substantially circular recess 12, having oppositely disposed flat sides a3, and adapted to contain interchangeable plates 4-5, the same having flanges 16 resting on the sliding cross-bar, and an extending annular ring 47 upon which may be placed the several layers of the fabric 50 to be out. These layers may be raised upward and pressed tightly together by actuating the end wheel 37, the upper layer resting tightly against the circular plate 52, positioned substantially central to the cylinder 15 and having its lower surface normally coincident with the corresponding surface of the bar 32. This disk may be retracted vertically by means of the stem 53, engaged with it and extending upward through the top bar lt and in which it may be clamped by the set screw 5 1.

In operation, the goods having been piled upon the plate 47, and the upper plate 52 secured in proper position, the crank 23 is operated, causing the knives 30 to descend from the cylinder and cut. the fabric into circular disks for whatever purpose they may be desired.

Havlng thus described my lnvention, what I clalm as new and desire to secure by Letters Patent is 1. In amachine of the class described, the

'head,and-a fabric clampingpress below said cylinder for holding goods to be operated upon.

2. In a machine of the class described, the

combination with a frame, a cylinder vertieally mounted therein, said cylinder being Copies of this'patent mav be obtained for screw-threaded, throughout, a cross-head suited to the threads, a bevel gear rotatably mounted below said cylinder, means for transmitting rotary motion to said bevel gear, connections between said gear and said cross-head whereby they are caused to rotate in unison, one or more vertical knives having cutting edges upon their lower ends carried by said cross-head, a slide vertically operable near the bottom of said frame, means for actuation thereof, a-detacl1able bushing carried in said slide, a clamp plate in 'alinement with said bushing movable through said cylinder, and means for clamping said plate in position whereby the fabrics may be tightly engaged between said disk and said bushing'in condition to be operated upon by said knives.

In testimony whereof I have signed my name to this specification.

SIMON GOTTLIEB.
